Cell Cycle Dynamics in the Microalga : Influence of Light Duration and Drugs.

Our investigation into 's cell cycle regulation involved natural and chemical synchronization methods to maximize their proportion at the division phase (G). Hence, cultures were grown under different light/dark cycles (24:0, 12:12, and 8:16 h) to assess the impact of extended dark periods on cell division. Flow cytometry analyses of the cell cycle revealed that extending the dark phase resulted in a higher number of cells entering G.

cds46, a highly variable carp edema virus gene.

Carp edema virus disease (CEVD) is a severe viral illness that causes substantial economic losses in wild and farmed common carp and koi. It is caused by carp edema virus (CEV), a member of the family whose genetic diversity and genome evolution are poorly understood. Based on a genomic fragment of the gene, two genogroups, genogroup I (gI) and genogroup II (gII), have been identified in samples of different origins.

Cell-state-dependent regulation of PPARγ signaling by the transcription factor ZBTB9 in adipocytes.

Peroxisome proliferator-activated receptor-γ (PPARγ) is a nuclear hormone receptor that is a master regulator of adipocyte differentiation and function. ZBTB9 is a widely expressed but poorly studied transcription factor that was predicted to interact with PPARγ based on large-scale protein-protein interaction experiments. In addition, genome-wide association studies (GWAS) revealed associations between ZBTB9 and BMI, T2D risk, and HbA1c levels.

Substrate stiffness alters layer architecture and biophysics of human induced pluripotent stem cells to modulate their differentiation potential.

Lineage-specific differentiation of human induced pluripotent stem cells (hiPSCs) relies on complex interactions between biochemical and physical cues. Here we investigated the ability of hiPSCs to undergo lineage commitment in response to inductive signals and assessed how this competence is modulated by substrate stiffness. We showed that Activin A-induced hiPSC differentiation into mesendoderm and its derivative, definitive endoderm, is enhanced on gel-based substrates softer than glass.
